4 So then I fear not an enemy's plots: one thing only do I fear, which is sin. If no one convicts me of sin, then let the whole world make war upon me. For this kind of war only renders me more prosperous. Thus also do I wish to teach you a lesson. Fear not the devices of a potentate, but fear the power of sin. No man will do you harm, if you dost not deal a blow to yourself. If you have not sin, ten thousand swords may threaten you, but God will snatch you away out of their reach: but if you have sin, even should you be in paradise you will be cast out.
Adam was in paradise yet he fell; Job was on a dung hill, yet he was crowned victorious. What profit was paradise to the one? Or what injury was the dung hill to the other? No man laid snares for the one, yet was he overthrown: the devil laid snares for the other, and yet he was crowned. Did not the devil take his property? Yes, but he did not rob him of his godliness. Did he not lay violent hands upon his sons? yes: but he did not shake his faith. Did he not tear his body to pieces? yes but he did not find his treasure.
Did he not arm his wife against him? yes but he did not overthrow the soldier. Did he not hurl arrows and darts at him? yes but he received no wounds. He advanced his engines but could not shake the tower; he conducted his billows against him, but did not sink the ship. Observe this law I beseech you, yea I clasp your knees, if not with the bodily hand, yet in spirit, and pour forth tears of supplication. Observe this law I pray you, and no one can do you harm. Never call the rich man happy; never call any man miserable save him who is living in sin: and call him happy who lives in righteousness.
For it is not the nature of their circumstances, but the disposition of the men which makes both the one and the other. Never be afraid of the sword if your conscience does not accuse you: never be afraid in war if your conscience is clear. Where are they who have departed? Tell me. Did not all men once bow down to them? Did not those who were in authority tremble greatly before them? Did they not pay court to them? But sin has come, and all things are manifested in their true lights; they who were attendants have become judges, the flatterers are turned into executioners; they who once kissed his hands, dragged him themselves from the church, and he who yesterday kissed his hand is today his enemy.
Wherefore? Because neither did he yesterday love him with sincerity. For the opportunity came and the actors were unmasked. Did you not yesterday kiss his hands, and call him saviour, and guardian, and benefactor? Did you not compose panegyrics without end? Wherefore today do you accuse him? Why yesterday a praiser, and today an accuser? Why yesterday utter panegyrics, and today reproaches? What means this change? What means this revolution?
